The code P0300 is a random misfire code which means any cylinder and the code P0316 means that there is a misfire code set within the first 1000 revolutions of the engine. Good luck with this problem.

Codes po308/po316


code po308 refers to cylinder 8 misfire detected===causes--engine mechanical fault---wiring---ignition/fuel system---injector--ECT/MAF sensors--ECM
code po316 refers to misfire detected on start up --first 1000rpm.===causes engine mechanical fault--wiring--ignition /l system--injector
For this I would be inclined to run a fuel system cleaner first to see f the injectors come good . Check all the wiring connections are clean and tight.

I have a 2007 ford taurus with p0300-p0303, p0306, p0316, p2195 and p2196. engine doesnt start anymore but battery is fine.


The old give me money for nothing statement from a mechanic instead of knowing how to fix it.
code p0300 refers to random/ multiple cylinder/s misfire detected===causes--spark plug/s---HT lead/s---injector/s---ignition coil/s--low compression--wiring
code po303 refers to cylinder 3 misfire detected--- engine mechanical fault---wiring---ignition/ fuel system---injector --ECT/MAF sensor --- ECM
code p0306 refers to cylinder 6 misfire detected===causes --engine mechanical fault---wiring---ignition / fuel system---injector ---ECT/MAF sensor---ECM
code po316 refers to misfire detected during start up--first 1000 revs==causes--engine mechanical fault---wiring---ignition /fuel system---injector
code po2195 refers to heated oxygen sensor (HO2S) 1 bank 1 signal stuck lean===cayses ---HO2S---fuel pressure---injectors---intake leak
it also refers to O2S sensor 1 bank 1 same causes and also refers to HO2S 1 bank 1 implausible signal===causes --- short to positive---short to ground---Ho2S ---ECM
code po2196 refers to the same items as 2195 . some causes are also air intake restricted
Have a compression test done some where else and it will indicate the condition of the motor. The rest is sensors and wiring problems.

2003 FORD ESCAPE CODES NEED TO KNOWN WHAT THEY MEAN PO316 ,PO306


PO316 is misfire on startup
PO302 is misfire on cylinder number 2

To find arc-over, start car at night, and look in the dark at the entire routing of the plug wire. I have seen where there was a faint glow the full length of a plug wire.

At a minimum replace the number 2 plug wire. Make sure it is seated on both ends and clean of corrosion.

Got a p0300 and a p0316 code on my 03 navigator it is running rough and losing power


CODE PO300 - RANDOM MISFIRE DETECTED. POSSIBLE CAUSES ENGINE HAS A MECHANICAL FAULT.CLOGGED OR FAULTY FUEL INJECTORS.FUEL PRESSURE TOO LOW OR HIGH FUEL SUPPLY CONTAMINATED.EVAP CANISTER FUEL SOAKED.EGR VALVE IS STUCK OPEN OR THE PCV VALVE SYSTEM HAS A VACUUM LEAK.COULD HAVE FAULTY IGNITION COIL OR BAD SPARK PLUG. MAF SENSOR CONTAMINATED IT CAN CAUSE VERY LEAN FUEL CONDITIONS. CODE PO316 - MISFIRE IN THE FIRST 1000 REVOLUTIONS

Changed all spark plugs 2 coils still getting po316 and po305 what could be causing this f150 4.6 liter problem started after putting in a new fuel pump


Diagnostic Test Code (DTC) P0316 means that a cylinder misfire was detected within the first 1000 revolutions of the engine crankshaft after engine startup. This code will always be stored at the same time with freeze frame data and a fault code for the offending cylinder.
This is where DTC P0305 comes in.
This code means that cylinder #5 is the cylinder that is causing the misfire.
Coils and plugs are only two of the many possible reasons for a cylinder misfire.
The possible reasons for both of these codes are:
> Damaged crankshaft position sensor
> Ignition system (Primary or Secondary)
> Faulty fuel injector or fuel injector control circuit
> Poor fuel quality (will usually cause MULTIPLE cylinder misfire codes)
> Base engine faults (burned valves, low compression, damaged lifters or cam, blown head gasket, etc.)
> Damaged/malfunctioning PCM

NOTE: The LEAST LIKELY cause is the PCM. A damaged Crankshaft Position Sensor will usually cause problems on ALL cylinders, not a single cylinder, however it IS possible if the sensing ring is damaged.

CODES-PO301-PO303-PO316- CHANGED PLUGS & WIRES. STILL MISS ON START UP, GOES AWAY MOST OF THE TIME ABOVE 1000 R.P.M


P0301 - Cylinder 1 Misfire Detected.

Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak

Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

P0303 - Cylinder 3 Misfire Detected.
Follow info from P0301.

P0316 - Misfire Occurred In The First 1,000 Engine Revolutions.

Causes:
- Damaged CKP sensor.
- Ignition System.
- Fuel Injectors
- Running out of fuel
- Fuel Quality
- Base engine
- Damaged Powertrain Control Module

Solutions:
Usually the P0316 is combine with a P03XX codes. The P03XX code indicates in which cylinder the misfire occurred.

I have a diagnostic trouble codes p1768,po300,and a po420. what does this mean?


I have tow of the three requested codes. po300 is misfire detected at multiple cylinders. See po301-306 represent the cylinder # misfire. So 301 is cylinder #1 misfire.

po420 is Catalytic Converter Efficiency Failure
